7 1/2'' 190mm DTH Bit With Tungsten Carbide Buttons For Water Well
Drilling
Product description
Down-the-hole (DTH) drilling has made it easier for contractors to
drill wells faster and more efficiently, and to transition from
dirt boring to rock boring just by adding a compressor and hammer
to the drill bit.

Product Advantages:
1. There are many designs and types of drilling bit used for
various drilling applications, and to suit different hammers.
2. The modern design of carbide button bit results in efficient
cutting of rock from the centre to the outer edges of the bit.
3. Button inserts are manufactured to high precision and to very
close tolerances. These are pressed into the body of the bit
resulting in an “interference fit”. This means that the carbide
buttons are very firmly held in the matrix and not easily dislodged
during the drilling process.
Face shape Features
Concave Face
1. Capable of drilling straighter holes in medium to hard rock
which is broken or less consolidated
2. Offers high penetration rate in the above stated rock conditions
3. Has excellent air flushing characteristics
4. Predominant face style for majority of drilling conditions
Flat Face
1. Have a superior performance in hard, abrasive and broken rock
conditions
2. They however have a slower penetration rate in comparison to a
concave face bit
Convex Face
1. This face has been designed to offer high penetration rate in
soft rock such as shale, limestone etc
2. They are recognized for having excellent capability for drilling
into moderately consolidated rock conditions
Product application
At present, DTH drilling tool is widely used in underground mining,
quarries, hydraulic and Hydro-Power Engineering, water well
drilling, Mineral exploration, anchoring hole drilling, geothermal
engineering, Subway excavation, another civil engineering.
DTH is one of the most efficient ways of drilling rock, using a
rapid hammer action to break the rock into sizeable chips which are
then evacuated from the bore hole by the air exhausted from the DTH
Hammer. The technique provides fast drilling of accurately aligned,
straight and clean holes in most ground conditions.
